Succession - the progressive replacement of one dominant type of species or community by another in an ecosystem, until a stable climax community is establishedPrimary succession - occurs on an area of land that has been newly formed or exposed such as bare rock. There is no soil or organic material present to begin with.Secondary succession - this occurs on areas of land where soil is present, but it contains no plant or animal species. An example would be the bare eather that remains after a forest fire.Deflected succession - when the direction of succession is affected by farming or other human activities such as mowing, grazing, burning crops etc.Pioneer species - the first organisms to colonise an areaSeral stages/sere - the steps in successionClimax community - final stage in succession, where the community is said to be in a stable statePlagioclimax - stage in succession where artificial or natural factors prevent the natural climax community from forming
